Dramatic, elegant, and deeply symbolic, this Solid Yellow Gold Celtic Knot Black Onyx Engagement Ring Set captures the powerful beauty of gothic and Celtic design. Solid Yellow Gold · 10K / 14K / 18K.
The engagement ring features a 1.4 carat pear-shaped black onyx, chosen for its deep black luster and striking contrast against warm gold. The gemstone is framed by intricate Celtic knotwork that symbolizes eternity and the interwoven paths of love.
Brilliant moissanite accent stones add luminous sparkle, balancing the dark center stone with radiant brilliance.
The matching contour band echoes the Celtic knot design, allowing the rings to sit perfectly together while maintaining their individual beauty. As a complete bridal duo it sits alongside our other wedding ring sets for women, and its bold pear-cut center makes it one of the most distinctive of our gemstone engagement rings. If a dark, symbolic stone speaks to you, our guide to non-traditional engagement rings is a helpful place to start.
Choose your gold: 10K, 14K, or 18K solid yellow gold
This Celtic knot set is crafted in solid yellow gold, and you choose your karat right from the drop-down. 10K is the most durable and most affordable option; 14K is our default, with a classic balance of durability and rich gold color; and 18K has the highest gold content for the deepest, warmest tone. The yellow color is permanent — solid gold never fades, chips, or turns your skin green — and other colors are available on request. If you're weighing the trade-offs, our 10K vs 14K vs 18K gold karat comparison guide breaks down exactly how the karats differ in durability, color, and price.

Frequently Asked Questions
Which metal should I choose?
All three options are solid yellow gold, so the choice comes down to durability, color depth, and budget. Choose 10K for the hardest, most affordable everyday wear, 14K for the classic balance most of our customers prefer, or 18K for the richest gold color and highest purity. You select your karat from the drop-down, and our karat comparison guide walks through the differences in detail.
Is this real solid gold?
Yes. This ring set is crafted from real solid gold throughout in your chosen karat (10K, 14K, or 18K) — never plated or gold-filled.
How do I care for the black onyx?
Black onyx is best cleaned with a soft, damp cloth and mild soap; avoid harsh chemicals, ultrasonic cleaners, and prolonged soaking, and store it separately to prevent scratches so it keeps its deep black luster.
